-point format is a data structure that specifies the fields that contain floating-point numbers, the layout of these fields, and their arithmetic explanations. Floating-point storage formats Specify how floating-point formats are stored in memory. These formats are defined by the IEEE standard, but the choice of which storage format is determined by the implementation tool.
Assembly language software sometimes depends on the storage format used, but higher-level languages typically deal only wit

Yesterday I read a book, "The Solaris Memory system," which wrote a lot about memory monitoring and memory optimization, as well as a software for memory monitoring, and the overall sense that the tool has a finer analysis of the memory of the Solaris system, It should be of great help when we solve the memory bottleneck.

Supporting heterogeneous environments takes far more time and effort than it takes to support only one hardware and software platform. The downside of the full use of a homogeneous platform is that the higher the server's performance, the faster the hardware it requires, the better the scalability, but the inexpensive x86 hardware used by desktops and small servers. To overcome this disadvantage and provide multi-platform support to users, Sun provides the Solaris operating System for x86 platfo

Lens Selection
Next, let's talk about the camera selection problem. This is a very troublesome problem and a big problem that is plaguing everyone's nerves.
What should I consider when selecting a lens:
1. image quality;
2. Price;
3. Portability;
4. convenience.
Aside from opening 1 and 2, although some old birds look down on those friends who choose to zoom in the dog mirror, it is obviously a bit funny to go out on a tour with a pair of dingjiao lenses, in terms of selection, you must also mak

The raft protocol is easier to understand and easier to implement than the Paxos advantage. It strengthens the position of leader, divides the whole protocol into two parts clearly, and makes some simplification by using the continuity of the log: (1) leader. By leader to the follower synchronization log (2) leader hung up, select a new leader,leader election algorithm.
But in essence, it is easy to place the process clear, the description is clearer, the key is to give a description of the pseu
